1.

Check the Vehicle Inquiry System (GMVIS) for in-service date and warranty blocks.

2.

Prior to removal and request of an injection pump, perform diagnostics based on symptom or Diagnostic Trouble codes (DTCs). For 1998 or older
vehicles, use the 1998 Service Information. For 1999 and newer vehicles, use the applicable service information for that year. Always utilize the Diesel
EFI Diagnostic Worksheet for all involved model years.

3.

Complete the entire Diesel EFI Diagnostic Worksheet by recording the values of the diagnostics performed. Photocopy the Diesel EFI Diagnostic
Worksheet form and attach the form to the repair order hard copy. When a defective injection pump return is requested, the repair order and Diagnostic
Worksheet must be returned with the defective injection pump.

4.

Record the serial number of the removed defective injection pump on the warranty repair order.
Important: Injection pumps received under this Special Policy have a serial number assigned and tracked to a specific VIN and TAC case. These
numbers are printed on the package label or packing slip. Parts numbers for Special Policy pumps are also different than injection pumps purchased
from GMSPO. It is imperative that technicians only install Special Policy Injection pumps on the assigned vehicle (registered TAC case). If a Special
Policy pump will not be installed in the assigned vehicle, call 1-877-446-8227 for disposition of the injection pump.

5.

Record the serial number of the new injection pump on the warranty repair order.

6.

Hold all defective injection pumps with a copy of the repair order and a copy of the Diagnostic Worksheet form until the Special Policy warrany claim has
been paid. A Corporate Parts Return Request will be generated. (Refer to Corporate Parts Return SI Bulletin 99-00-89-019B. All associated failed parts
for claims paid under this Special Coverage, including the defective diesel injection pump, will be returned to the Warranty Parts Center (WPC).
Important: Failure to retain the defective pumps as required above violates the General Motors Service Policies and Procedures, Article 1.7, with a
minimum of $800 (US) debit. Removed defective injection pumps ARE NOT to be sold by the dealer for remanufacturing, rebuilding or scrap. Under no
circumstances are the injection pumps to be installed on any vehicle, sold at retail, or used in any other application.

•

The defective diesel injection pump metal identification tag must remain attached to the injection pump to avoid a claim debit.

•

All components must remain on the defective diesel injection pump, including: pump-mounted driver, electric fuel shut-off solenoid, stepper motor, etc. in
order to avoid a claim debit.

7.

The servicing dealer is authorized to submit a Special Policy warranty claim for pump replacement labor time, plus 0.2 hour administration. (See Claim
Table ***).

Important: Damage from poor quality or incorrect diesel fuel, or gasoline or water contamination is not covered under the terms of the 6.5L diesel warranty.
For proper diagnostics, refer to SI Bulletin 99-06-04-047A in order to determine if the vehicle fuel system contains metal contamination. Be sure to complete the
correction for vehicle fuel system metal contamination before installing the new electronic diesel fuel injection pump.
